Variable spliced aluminum alloy die

The utility model relates to the technical field of wallboard dies, and particularly discloses a variable spliced aluminum alloy die which comprises at least two side dies, the side dies are arrangedside by side, placing grooves are formed in the two ends of each side die, a matching cavity is formed by the placing grooves in the end faces of every two adjacent side dies, a fixing piece is detachably connected in each matching cavity, and the fixing pieces can be clamped with the matching cavities. According to the utility model, the placement grooves are formed in the fixing pieces and the side molds; after the side molds are placed side by side, the two side molds can be fixed through the fixing pieces, and therefore the multiple side molds can form the forming mold, wallboards with different thicknesses can be formed through the forming mold, and the problem that in the prior art, a wallboard mold cannot flexibly manufacture wallboards with different thicknesses is solved. 本实用新型涉及墙板模具技术领域，具体公开了一种可变式拼接铝合金模具
